It depend on the material being televised. Im just curious though. Why will any white person whether non-african , in Africa or of mixed African descent like you said want a white televesion channel.
The entire media is all white.
In Africa it makes sense that majority of the channels are televise black stuff (HEY its africa). But lets even leave the domain for a second. There are prmarily black this and that like TV, scholarships , colleges because as a race, slacks have been denied alot. Did you know before the 1960s/70's blacks in the US werent allowed to be enrolled in regular collges ? All the US had were channels that wouldnt play black entertainment material like music. BET had to rise to it. Like Zuri said, black TV was a result of resistance.
The list goes on & on.
So even if its pushed for, i think the material will decide
